tain: new and useful Improvements in Movlug-Picture Gamer-es, of which the following is a specification.

' The object of the present invention is first,

to provide it camera" capable .of taking a sensitized film as distinguished from the ordinary intermittentlymovable film.

To this end, the invention comprises a. moving picture camera having manually operated means for constantly moving a sensitized-film through the optical field in combinationwith a. suitahle shutter adapted to intermittently expose the film, end a lens mounted in a suitable carrier provided with menus for moving it downwardly. at the same rate of speed as the travel of the film during the instant of exposure, and upwardly at a greater rate of speed during the period that the shuttenis closed, the carrier moving means comprising a variable-leverage lover operatively connected to the carrier and th driving mechanism. The rapid "upward or return movement of. the lens pluses it in position to again move downwardly at the next exposure of the film. By this means, the successive exposures are made through the lens traveling in the some direction and at the some speed as the constantly moving film. The film, the shutter and the reciprocnting lens are all driven through properly proportioned devices opcruted by the usual hand crank.

In order that my invention ---1nuy be fully understood, I will first describe the some with reference to the accompanying drawings and afterward point out the novelty more particularly in the annexed claims.

In said drawings: Figure 1 is a vertical longitudinal. sectional view of :1, moving pic thereto. Fig. 2 is a. vertical transverse sectlOIlELl view oi: the some. Fig. 3 1s :1 detail side elevation on a larger scale of the lens Fig. l 1s a front view of operating device. the same.

l is the usual cumcra box formed in its rear wall with an opening 2 leading into :1 focusing tube 3 which is formed in its inner end with the plates or flanges 4 over which from the spool 6 over the guide roller 8 above the top flange l and across the optical field to the lower guideroller 9 and from there to the winding spool 10 which is suitably fixed upon a shaft 11 journulcd in a bearing 12 secured to the inside of the cam era box. The shaft 11 extends through the side wall of the camera box and is provided with a orunk'handle 13 by which the winding spool '10 is rotated for drawing the film '2' constantly through the optical field and winding it upon the spool 10.

It will be observed that the winding spool 10 has a. cylindrical body between its flanges of relatively large circumference so that the increase in circumference in winding the Whole length of film upon the spool will be so slight that there will be no appreciable change in speed of the travel of the film so far as practical results are concerned.

is the rotary shutter formed with the radial exposure opening 16. The shutter 15 is suitably journaled' upon a bracket arm 17 and is provided with u snihll bevel l8 meshing with a similar gear 19 keyed to c. shaft 20 journuled in a. suitable hearing (not shown) end gurryin g at its outer end :1 gear wheel 21 driven by the train of gears 2'12, 23, Ql, 25. The gear is keyed to a. shaft 26 supported in suitable hearings and carrying a sprocket wheel 27 driven by u sprocket chain 528 and driving sprocket wheel 29. The sprocket wheel 2-9 is fined upon the hand operated shalt ll. By the train of mechanism described, it will be understood that the shutter 15 is constantly rotated to intermittently expose u section of the constantly, travelingsensitized film 7.

The front wall of the camera casing is provided with an opening 30 in line with the rear opening 9-. Mounted in this opening 30 is the lens tube carrying the usual lenses such as indicated at The lens tube 35 is formed with a wide circular flange 37 which fits snugly against the front wall of the camera bow: and completely shuts out the light from the opening 30. it will be observed that the opening 30 is materially larger than the diameter of the lens tube earl ill
